�鶹�� Vine Customer Review of Free Product( What's this? )
Could not wait for this to arrive it arrived today we put it together as soon as it showed up. My son and I built it together. He definitely needed an adult help. I mean, he probably could’ve done it. It just would’ve taken a lot longer. He was so excited to play with it when it was done. The build itself was pretty relaxing at the same time exciting. Watching this thing come together was awesome. Watching him play with it when it was done was even better. Lego is known for their quality pieces. A decent said for the price. I’m personally not a huge fan of this theme but sets like this. It doesn’t matter what theme it is they’re cool. It is a pretty good value, especially if you get it on sale.

�鶹�� Vine Customer Review of Free Product( What's this? )
This is a really awesome model. The articulating joints and size make it feel like something you pose and display, but it can be played with as well. My kids are big Ninjago fans and this kit is really a great item. Definitely for older kids or adults, as the large number of pieces and sheer detail mean that small children may not have the patience to complete it.

Slick looking mech

Let's face it, official LEGO predicts just have better build logic and instructions. This set is impressive and colorful: great for any LEGO or Ninjago fan. If you've built Voltron, you know large mech offerings are solid and probably a better value offering then any licensed product.
